Lightly whisk the eggs, milk and parsley with a fork until combined. Season with a little salt and pepper.
Melt butter in a small frying pan over medium heat. Pour the egg mixture into pan. Don’t stir eggs until they begin to set, then push cooked egg into centre with a wooden spoon or spatula and allow uncooked egg to touch the base. Cook until eggs are just set and scrambled. Remove from the heat.
